Glenn Circle East Dam dam
Glenn Circle East Dam
Glenn Circle East Dam, located in Plainfield, Illinois, along Wolf Creek, was completed in 2003 by INTECH and serves as a crucial flood risk reduction structure in the area. The earth dam stands at a height of 7 feet and spans 100 feet in length, with a storage capacity of 274 acre-feet. Despite its low hazard potential and moderate risk assessment, the dam is state-regulated by the Illinois Department of Natural Resources (IDNR) and undergoes inspections every five years to ensure its structural integrity.
Owned privately, Glenn Circle East Dam has a primary purpose of flood risk reduction, with its design classified as an earth dam with buttress core types. The dam does not feature any outlet gates or controlled spillways, but its uncontrolled spillway width is recorded as 0. The surrounding area of Will County, Illinois, benefits from the dam's presence, offering protection against potential flooding events. With Lauren Underwood (D) serving as the Congressional Representative for the district, the dam remains an essential component of the region's water resource management infrastructure.
Water resource and climate enthusiasts can appreciate the significance of Glenn Circle East Dam in mitigating flood risks along Wolf Creek in Plainfield, Illinois. As a state-regulated structure with a low hazard potential, the dam plays a crucial role in safeguarding the surrounding community from potential inundation. Its completion in 2003 and continued state oversight ensure that the dam remains a reliable flood risk reduction measure in the region. The structure's design, construction, and operational details provide valuable insights for those interested in water resource management and climate adaptation efforts in the area.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Glenn Circle East Dam
Where does the data for Glenn Circle East Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
